Description

Technical Field

[0001] The utility model belongs to the technical field of bridge deck guardrail spraying, and specifically relates to a guardrail spraying device. Background Art

[0002] After the construction of the bridge is completed, with daily use, the ancillary facilities may be damaged. As one of the ancillary facilities, bridge guardrails are very common to suffer from paint loss and rust.

[0003] At present, the maintenance of guardrails on bridges is mostly done manually. Maintenance personnel regularly go to the bridge to check and repair, which is time-consuming and labor-intensive, and the maintenance of guardrails is lagging. When maintenance is carried out, maintenance personnel need to carry tools and equipment to the bridge, and must occupy the road for construction when necessary. In addition, the outside of the guardrail is not easy to observe and construction is difficult, which increases the insecurity of maintenance. In addition, if maintenance is not timely, serious damage to the guardrail will bring immeasurable harm.

[0004] To this end, for example, the anti-rust spraying equipment disclosed in the Chinese utility model patent "Anti-rust spraying equipment for bridge guardrails" has a patent number of CN201921304404.4 (authorization announcement number is CN210846869U). Although it can spray the guardrail, when rust is severe, direct spraying will cause the sprayed paint to fall off easily.

[0005] Therefore, it is necessary to further improve the existing guardrail spraying device. Utility Model Content

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 6 As shown, the guardrail spraying device of this embodiment is used to treat the guardrail. The guardrail spraying device includes a spraying device 1 and a grinding device 3. The spraying device 1 is installed on the base 21 of the guardrail 2, and the spraying device 1 has a spray head 11 for spraying paint. Figure 6 As shown, the aforementioned paint spraying device 1 also includes a storage bin 12 for storing paint and a third telescopic rod 13 that can be telescoped up and down, the upper end of the third telescopic rod 13 is connected to the spray head 11, and the lower end of the third telescopic rod 13 is connected to the base 21 through the storage bin 12. In this embodiment, the spray head 11 is connected to the third telescopic rod 13 through a fourth telescopic rod 14 that can be telescoped forward and backward, and a second camera 6 is provided on the outer side wall of the fourth telescopic rod 14 at a position adjacent to the spray head 11. The presence of the second camera 6 can observe the degree of spraying paint on the guardrail.

[0029] like Figure 2 and Figure 3As shown, the grinding device 3 is installed on the base 21 of the guardrail 2 and is arranged on the same side as the paint spraying device 1. The grinding device and the paint spraying device are located on at least one of the front and rear sides of the guardrail 2. In the present embodiment, the grinding device and the paint spraying device are both located in front of the guardrail 2. The aforementioned grinding device 3 includes a bracket and a grinding head 32 for grinding the rusted parts of the guardrail 2. The grinding head 32 is arranged on the bracket and faces the guardrail 2. The grinding device 3 and the paint spraying device 1 are arranged at intervals along the left and right directions, and are both slidably constrained on the base 21 along the left and right directions. Specifically, a slide rail 211 extending along the left and right directions is provided on the base 21, and the slide rail is located on the front wall surface of the base 21. The bottom of the bracket and the bottom of the paint spraying device 1 are both equipped with a rotating wheel 5 that slides with the corresponding slide rail 211. In order to increase the smoothness of the movement of the painting device and the polishing device, a guide rail 212 extending along the left and right directions is opened on the top surface of the base 21, and a driving wheel 7 that slides with the corresponding guide rail 212 is installed at the bottom of the bracket and the bottom of the painting device 1 at the position corresponding to the guide rail 212. The aforementioned driving wheel 7 can rotate under the drive of the second motor 71.

[0030] like Figure 1 As shown, the bracket is a first telescopic rod 31 that is arranged vertically and can be extended up and down. The upper end of the first telescopic rod 31 is connected to the grinding head 32, and the bottom end of the first telescopic rod 31 is connected to the base 21. Figure 5 As shown, the grinding head 32 includes a housing 321, a grinding brush 322, and a first driving mechanism for driving the grinding brush 322 to rotate around its power output shaft. The grinding brush 322 is arranged on the side of the housing 321 facing the guardrail 2. The first driving mechanism is arranged in the housing 321, and the power output shaft of the first driving mechanism is connected to the grinding brush 322. Specifically, the interior of the housing 321 has a chamber 3211 opening toward the guardrail 2, the first driving mechanism is located in the chamber 3211, and the grinding brush 322 is blocked at the opening. In this embodiment, the first driving mechanism is a motor 324.

[0031] In addition, in order to move closer to or away from the guardrail, the grinding device 3 also includes a second telescopic rod 33 that can be extended forward and backward and can swing up and down relative to the first telescopic rod 31. The first end of the second telescopic rod 33 is rotatably connected to the first telescopic rod 31, and the second end of the second telescopic rod 33 is relatively fixedly connected to the grinding head 32.

[0032] In order to observe the grinding degree of the guardrail, a first camera 4 is provided on the outer side wall of the second telescopic rod 33 at a position adjacent to the grinding head 32 .

[0033] The first, second, third and fourth telescopic rods mentioned above have the same structure as the telescopic rods in the prior art, and will not be described in detail in this embodiment.

[0034] The guardrail base in the above-mentioned spraying device needs to complete the arrangement of the slide rails and guide rails during construction. It must be ensured that there are slide rails on both sides of the guardrail, and every 100 meters, there is an intersection between the slide rails on both sides, where the slide rail guardrail spraying device can slide to the outside for maintenance operations. Usually there is a charging pile at the intersection, and the guardrail spraying device is docked at the charging pile for charging when not in operation. The inspection cycle can be set according to demand, and the spraying device is inspected regularly. The first and second cameras can be used to monitor whether there are rust, damage and other diseases on various parts of the guardrail. If rust is encountered, the second telescopic rod of the grinding device automatically extends, and the grinding head automatically aligns with the rusted part for grinding. After grinding is completed, the spraying device will move to the polished part and spray paint the polished part. After painting is completed, the fourth telescopic rod will automatically retract and continue the patrol operation. The painting device and the polishing device perform assembly line operations; the paint required by the nozzle is in the storage bin; when the paint storage bin is insufficient, a reminder can be sent to the maintenance center to remind the maintenance personnel to add paint therein. When the spraying device is charging at the charging pile, the photos or video data taken by the camera can be transmitted to the maintenance center through the line for the maintenance personnel to record and analyze.
